`NORMAN KNOWLES AND WILLIAM PHILIPSON, OF BOLTON, COUNTY OF LANCASTER, ENGLAND.

CIRCULAR BRUSH.

SPECIFICATION forming part of Letters Patent No. 417,566, dated December 1'?, 1889. Application filed September 12, 1889. Serial No. 323,730. (No model.) Patented in England October 27, 1888, No. 15,480.

To all whom it may concern:

Be it known that We, NORMAN KNOWLES, cotton-spinner, of Egyptian Mill, Bolton, and WILLIAM PHILIPsoN, engineer, of Holland Street Iron Works, Astley Bridge, near Bolton, both in the county of Lancaster, England, have invented new and useful Improvements in Circular Brushes, (for which we have obtained apatent in Great Britain, No. 15,480, dated October 27, 1888,) ot' which the following is a specification..

The object of this invention is to -make brushes with long bristles as effective as those with short bristles, thereby dispensing with the necessity of cutting or singeing the brisfles of new brushes, so common at the present time.

It is a well-known fact that long bristles in brushes are weak, owing to their length. Consequently they bend when operating on the surfaces they are intended to clean, which diminishes the brushing or cleansing power of the same, as well as wearing the side of the bristles. To overcome this defect it is a common practice to shorten the length of the bristles by cutting or singeing, which causes the brushes to be speedily worn out.

Figure l is a sectional elevation of our improved circular brush. Fig. 2 is a longitudinal elevation, and Fig. 3 is a sectional elevation through line A B in Fig. 1.

On the center A is secured the block or body B, provided with the slots or recesses C, to receive the adjustable bristle-stocks D. The perforated Aplates E are secured to the block or body B by the screws F. The bristles I-I protrude through the perforations G in the plates E,as shown in Figs. 1 and 3. The bristlc-stocks D are operated in either directioni. e., up or down-in the slots or recesses C by the screws I, according to the length of bristle or the amount of rigidity required. The screws I are mounted in the bottom end on the plate K', and are secured bythe plates u L and screws M. The screws I pass through Several screws I are provided in the length of the brush to increase the stability or iirmness of the brush-stocks D, to prevent bending or deliection when the brush is in opera-` tion.

Each end of the brush-block or body B is fitted with the metallic ends P, secured by 6o screws or their equivalents.

In circular brushes at present employed for stripping carding-engine cylinders and doffers the bristles are placed spirally once round the body in the length of the brush, whereas according to our present invention the spiral is formed in about one-fifth, or thereabout, of the diameter. Owing to the spirals of our improved circular brush being reduced in length and the firmness of the 7o bristles increased, the same can be driven or rotated at a much slower speed than hitherto, which will prolong the life of the same and effect a great saving in the cost of renewals.

This improved brush is equally applicable for carding-engines and combing and other machinery wherein circular brushes are employed.

If desired, our improved brush can be made without spirals, the slots in the block orbody 8o B being formed in line with the center line of same.

The brush-center A is provided with the pulley R, by which it can be driven from any convenient source.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is y In a circular brush, the combination, with the body B, having the slots or recesses C, 9o bristle-stocks D, and perforated plates E, of the screws I, mounted in the bottoms of the slots C, having a threaded engagement with' the bristle-stocks, and adapted to be operated through the plates E to move the said bris- 95 tle stocks, substantially as described.

In testimony whereof we afIiX our signatures in presence of two Witnesses.
